Hemophilia

Hemophilia is Inherited Blood Disorder Resulting Severe Bleeding
Haemophilia is a rare human blood disorder in which blood clots very slowly, resulting often in severe bleeding internally and externally. The condition is due to a lack of fibrin in the blood and is controlled by two closely linked genes on the X-chromosome that are responsible for the production of different clotting factors. Haemophilia A individuals lack antihaemophilic factor, while haemophilia B individuals lack plasma thromboplastin. Males carrying the mutant alleles will be affected, although heterozygous females have normal blood. The patient may experience prolonged bleeding following any injury or wound. Haemophilia may be treated by transfusions of plasma (which contains the missing factor).
